Abstract: PROBLEM TO BE SOLVED: To measure the lights scattering at different scattering angles simultaneously by adjusting each detector at 0 deg. position relatively to a laser beam such that all detectors on a rotary table are directed toward a common point at the center of rotation. SOLUTION: In the measuring equipment, a sample 3 in a container 5 containing a liquid 4 having refractive index identical to that of cuvette glass is irradiated from a laser light source 1.

Scattering light from the sample 3 is detected by a large number of detectors 8 juxtaposed on the rotary table 7 at an arbitrary angle. Each detector is adjusted, by respective adjuster, at each 0 deg. position relatively to the laser beam such that all detectors 8 are directed toward a common point at the center of rotation. According to the arrangement, the lights scattering at different scattering angles can be measured simultaneously.

Title: Transistor circuit
Inventor: OSANAWA TATSUHIRO
IPC: H03F3/34
Filed: 1982-05-17
Abstract: PURPOSE:To suppress heat generation in the chip of an IC or individual parts by allowing an external resistance to consume a part of elecric power generated by a saturated voltage developed between the collector and emitter of a Darlington- connected TR circuit while holding the saturated voltage on the same level as before. CONSTITUTION:In the figure, 7 and 8 are TRs in the IC chip, 8 is a TR with low collector series resistance, and 9 is a resistance outside of the chip. The resistance 9 consumes the electric power of the collector current I8 of the TR8. The current saturated voltage is a higher voltage between the sum of the forward base-emitter voltage Vbe8 of the TR8 and the collector-emitter forward voltage Vsat7 of the TR7 and the sum of the saturated voltage Vsat8 of the TR8 and the voltage Vr developed at the resistance 9. Then, the Vr is the product of the valve R9 of the resistance 9 and the collector current Ic of the TR8, so when the value R9 of the resistance 9 is set to (Vbe8+Vsat7-Vsat8)/Im where Im is the maximum value of the current I8, Vbe8=Vsat8+Vr. Namely, by inserting the external resistance having a proper value fot the current I8 as shown in the drawing, a part of the electric power supplied to the IC, etc., can be consumed externally without raising the saturated voltage.

Title: Ship
Inventor: SAWAI KENJIROU
IPC: B63H11/08
Filed: 1980-06-12
Abstract: PURPOSE: To obtain a large amount of propulsive power, by injecting water in an opposite direction to the sailing direction of a ship with the rotary action of an impeller.  
     CONSTITUTION: When a ship body is floating on the water, insides of a water conduction duct 4 and casing 6 are fully filled with water. Under this condition if an impeller 9 is rotated, water in the inside of the casing 6 is compressed by the rotary action of the impeller 9, fed out to a tangential direction and jetted into the water from an outlet 8' of a discharge cylinder 8. This water is jetted in an opposite direction to the sailing direction of a ship, further the water being jetted at acceleration of w 2 r because of an effect of rotary action of the impeller 9 can generate a large amount of propulsive force, thus the ship body is moved by said propulsive force.

Abstract: PURPOSE: To prevent creasing of paper at the pressure fixing by so forming the electrophotographic recording paper using pressure fixing that the rate of reduction in its thickness with respect to its initial thickness has pressure dependency of more than the specific value within the specific range of pressure stress.  
     CONSTITUTION: With the recording paper of either case of the case when copies are obtained by direct fixing after development or the case when they are used for transfer process in an electrophotographic method, the paper of which the rate of decrease in its initial thickness has pressure dependency of 2.5×10 -3 %/kg/cm or more with respect to pressure stress of a range of 0Wabout 4,000kg/cm 2  is used. If this recording paper is used, the strain that becomes the cause for the occurrence of paper creasing accumulated in the paper at the pressure application can escape owing to the change in the paper thickness and becomes therefore small in accumulation amount, and this prevents the occurrence of paper creasing. Such recording paper may be readily obtained by making paper-making conditions and the treating conditions at the rolling by calender rolls proper.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage to segments by the effect of heat and to suppress the temp. fall of a strip by multiple fitting plural metallic pipes and subjecting the respective pipe layers to a thermal insulation treatment between each other. SOLUTION: The sleeve is formed of a multiple fitting structure of the metallic pipes (circular pipes) 1 and thermally insulating material layers 2 are interposed between the pipe layers. The thermally insulating material layers 2 are formed by applying a soln. consisting of a thermally insulating material as a solute on the outside surfaces of all the circular pipes 1 exclusive of the outermost pipe and drying the coating prior to the fitting of the metallic pipes. Since the respective metallic pipes are fitted by an interference fit (shrinkage fit), the slip does not arise between the circular pipes during strip taking-up. The thicknesses of the outermost pipe and the innermost pipe are made larger than others in order to obtain high rigidity.  The sleeve is fitted to the take-up machine segments around which the high-temp. strip is wound to prevent the temp. fall of the strip and to prevent the damage of the take-up machine segments. The surfaces of the respective metallic pipes are preferably provided with spiral grooves.
